The photo is just part of the first roost. It continued up the first tree. There were 3 roosts total.

Time of day you first saw the roost:
3pm they started flying in and around the yard from the fields.

Date the roost first formed:
For the past couple of weeks we have had roosts on and off. Yesterday we had a bunch show up again. There was 3 total roosts last night with butterflies clustered together.

Nectar sources nearby like clover, alfalfa fields or wildflowers:
Yes all of the above! We have hay fields and fields full of Goldenrod and also my pollinator gardens as we are a Monarch Waystation with Monarch Watch.

Overnight temperatures:
Low projected at 52 tonight.

Wind direction. Were the monarchs shielded from the wind in this location?: NW wind- a mild breeze at the moment, we are on a ridge so very little protection from wind, but the monarchs are all on my line of windbreak Hybrid Willows on the end of the tree line all facing east. I think to stay protected from the wind direction.

How you counted or estimated the number of adults roosting:
I counted the ones I could and then started to estimate.
